For those still enjoying the smell of smoke. It is normally a minority of ex-smokers who continue to like the smell of smoke. The fact is these people can be around smokers and their quit can and will stay secure as long as they don't puff on a cigarette themselves. But as far as asking people to blow smoke your way, there is a philosophical question they should be asking yourself.
Do you want to give smokers the idea that you somehow miss smoking or that the smoker has something going really good for themselves? Keep in mind, these smokers can be looking at you as a person who used to be just like them--an out of control addicted smoker who has now quit and appreciates being smoke free. But by asking them to blow smoke your way, you are giving them the perception that you have sacrificed something great in your life and may be giving them the message that you somehow regret your quit. You may in fact be discouraging them from quitting.
So my advice to you, if these people are your family members or friends, or any people you actually care about, such requests while seeming harmless to you may in fact be hurting their chances of quitting. Do you really want to encourage these people to smoke? If they are people you don't care about this is probably no big deal--although do you even want strangers to be putting their life at risk in order to feed an addiction.
Your quit is for you though. This is a straight judgment call on your part. As I said before, you can be around such exposure without relapsing--but think very carefully of what kind of message you are sending others and also what you are thinking about smoking for yourself. If you still see cigarette smoke as a good thing, you could probably stand to read through The Palmolive Bottle Demonstration

One more thing--while I say that second hand smoke exposure will not cause a relapse--there can still be adverse health effects from such exposure. Don't think because you like the smell that this means the smoke is not hurting you. Hydrogen cyanide smells sweet--almost like almonds yet it is highly toxic and potentially lethal. Smells can be deceiving. See cigarettes for what they are and they will automatically stink to you--not only for how they smell but for what they do. Cigarette smoke kills people, lots of people and if given the opportunity will kill you. To avoid stinking up your life and messing up your health always remember why you committed to never take another puff!
